There really isn't a number I can give you. I can however suggest that if you are sexually active you need to get the HPV vaccine. It is a 3 shot series and is recommended right around your age. If you are having any kind of sexual contact then there IS a chance of getting HPV. If it is both of your first times then the chance is small, but you can never be sure your partner is only seeing you; especially at a young age.

You should have a conversation with your parents about the HPV vaccine. While it is for an STD its primary purpose is to prevent cervical cancer that is caused by HPV. The CDC recommends all teens to get the shot. Ultimately the only way to prevent STDs is to not have sex. I'm sure you have heard that lecture before but it is the unfortunate truth.

Be sure to always use condoms if you are having intercourse of any kind. I don't know exactly what you and your boyfriend do with each other and you are pretty young but I'm assuming if you are asking about STDs then you are having sex.On that note you cant get HPV from just kissing, but as soon as any of the genitals are involved then you have a chance (whether its hand oral or full intercourse)

Finally, I do advise that you don't have sex, you are very young and there can be a lot of big problems that come with sexual activity, not only STDs but if you did get pregnant at that age there are serious complications that can arise for you.

low. Very low. It's possible he was transferred hpv during birth, but that's unlikely. Most 13 year olds shouldn't be sexually active anyway. You shouldn't even be having sex, even if you think about it, find something productive to do instead.

Fairly low... however do to the rise in HPV doctors say within the next couple years ever body will have gotten HPV atleast once in their lifetime. But relax it natural leaves the body within 2-3 years.
